Summary

CVE-2025-62594 is a medium-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Imagemagick Imagemagick. Its CVSS base score is 4.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 27th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

Vulnerability Data

ImageMagick is a software suite to create, edit, compose, or convert bitmap images. ImageMagick versions prior to 7.1.2-8 are vulnerable to denial-of-service due to unsigned integer underflow and division-by-zero in the CLAHEImage function. When tile width or height is zero,…

more

unsigned underflow occurs in pointer arithmetic, leading to out-of-bounds memory access, and division-by-zero causes immediate crashes. This issue has been patched in version 7.1.2-8.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

The vulnerability enables an application-layer denial-of-service via out-of-bounds memory access and division-by-zero in the CLAHEImage function, directly mapping to T1499.004 (Endpoint Denial of Service: Application or System Exploitation).

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires applying the vendor patch (7.1.2-8) that eliminates the unsigned underflow and divide-by-zero in CLAHEImage.

prevent

Enforces validation of image metadata (tile width/height) before CLAHE processing, blocking the zero-value inputs that trigger CWE-191/CWE-369.

prevent

Provides memory protection mechanisms that can contain or prevent exploitation of the out-of-bounds access (CWE-119) resulting from the underflow.

detects

Security testing in development catches out-of-bounds accesses before release, covering most instances of the weakness.

prevents

Secure development lifecycle mandates memory-safety practices that directly prevent buffer-boundary violations.

prevents

Application security requirements can specify memory-safety rules, but do not prescribe implementation details.

prevents

Secure architecture and engineering principles include memory-safe design patterns that mitigate buffer overflows.

prevents

Secure coding standards explicitly forbid unsafe buffer operations, directly eliminating CWE-119.
